human brain has tripled in size‚ with most of the growth being seen in just the last two million years. Although many explanations for the growth of the human brain have been presented‚ one hypothesis that proves to be most accurate is the Social Brain Hypothesis as presented by Robin I.M. Dunbar.

Permanent Income Hypothesis Introduction The basic idea is that people’s income has a random element to it and also a known element to it and that people try to smooth the random part using saving and borrowing.

The skeptical hypothesis seeks to undermine the credibility of our knowledge by making a claim about the falsity of our beliefs that we cannot disprove. I will explain this hypothesis in further detail and outline two responses to it‚ the Moorean response and the contextualist response. Finally‚ I will argue that the Moorean response is the most logically sound of the two‚ while considering a counterpoint to the Moorean philosophy. The skeptical hypothesis argues that for anything that one might
